Installed F40 beta KDE and have no sound. Tried all possible ports and profiles out. No luck. Under Windows all works fine.
What could be the problem?

The device information
I haven’t test on 40 but on 39 with the AE-5 Plus I need to install alsa-firmware… You can also extract the package and manually copy the files in the ca0132 folder to /lib/firmware/… You don’t need to move the whole folder, just the files to /lib/firmware/… For some reason 39 doesn’t install that firmware by default and the Kernels built in support is spotty without them…
If you check dmesg you will probably see a message from snd_hda_intel saying ctefx.bin and ctefx-desktop.bin could not be found or loaded. It’s because the files are missing.

BTW I have problems with SB. After PC is waked up, it does not work, I have to manually restart Pipewire… Does anybody experience the same?
